R Studio Latest Version on Mac

I have downloaded R Studio Desktop on my MacBook Pro, but I do not believe it is the latest version. I am unable to install certain codes because of this. For example, I receive this message:

install.packages(“car”)
Warning in install.packages :
package ‘car’ is not available (for R version 3.3.3)

Any help would be appreciated,
Thank you
